Vanilla Yogurt - Machine

Home made yogurt is nothing like the commercial stuff and using an inexpensive machine (mine was $25 on Amazon) makes it easy. By omitting the vanilla extract and sweetener, you can make plain unflavored yogurt for savory dips. My daughter claims that letting the recipe ferment in the machine for 24 hours makes the yogurt lactose free. I don't know if that's true but she is lactose intolerant and eats this recipe daily.
